In Nasu-miso, stir-fried aubergine is coated in a rich miso sauce. Make sure the oil is smoking hot when adding the aubergine pieces, so that they do not absorb too much oil.
Cut the aubergines into bitesize pieces and place in a large colander, sprinkle with some salt and leave for 30 minutes to remove the bitter juices. Squeeze the aubergine pieces by hand. Remove the seeds from the chillies and chop the chillies into thin rings.
